Specification of Letters Patent.

Patented Oct. 24, 1911.

Application filed February 23, 1904. Serial No. 194,875.

To all whom it 'may conccm:

Be it known that I, ARTHUR Barns, a subject of the King of England,residing at Leicester, in the county of Leicester, England, haveinvented certain new and useful Improvements in or Relating to Pulling-Over Machines, of which the following is a specification.

This invention relates to pulling-over or like machines, its objectbeing the improvement of, for example, such a pulling-over machine as isdescribed in the specilication of Letters Patent of the United StatesNo. 663,777, issued December 11, 1900, on the application of Ronald F.McFeely, with the object of securing more satisfactory positioning andfitting of the uppers on their lasts, especially when the machine isoperating on uppers not formed initially to lit dead to the last, butwhich are formed initially to have what is commonly termed spring, thisspring necessitating a drafting or stretching of the material in adirection longitudinally of the last to secure a proper fitting of theupper thereto. This formation of the uppers with spring is generallycustomary in British boot manufacture.

ln the pulling-over machine above referred to by way of example thereare in addition to the toe gripper, two side grippers for engagingopposite sides of an upper placed on the last, and yielding means bywhich the relative position of the last and grippers is changed toeffect the updraw and means for securing the upper after it has beenpulled.

According to this invention a side-gripper has combined therewithdevices which will automatically cause the gripper to move in such adirection in relation to the last as to impart, for the purpose ofdealing with the spring, both :toredraw and updraw to a part or tocertain parts of the upper. lVliere two or more side-grippers areemployed it is part of the present invention to combine therewith eitherhand-operated or power-operated mechanism which moves either manually orautomatically diierent grippers simultaneously in like or in differentdegrees to impart for the purpose described like or different degrees oforedraw movement, prior to or at the same time as or subsequently to theupdraw, to certain parts of the upper.

The extent of the foredraw movement imparted .to the side-gripper orside-grippers in relation to the last according to this invention may bevariable. The means for obtaining the oredraw may also include `ayielding device which will yield under excessive stress and prevent anydamage being done to the work being operated upon. To enable that partof the mechanism which elfects the foredraw to be put into or out ofoperation when desired a control device may be combined with themechanism and operated by means such for example as a hand lever orpedal, or otherwise.

The present invention comprises also the combination in a pulling-overor like machine, with a last, a side gripper and means by which therelative position of the last and gripper is changed to effect theupdraw, of a sliding or other guiding device which, while the updraw istaking place, constrains the gripper to have a positive motion in thedirection -o'l the length of the last. The said sliding or guidingdevice imparts :a foredraw movement, which is additional to andsimultaneous with the updraw movement, to the part of the upper grippedby the gripper, for the purpose of so pulling upon a portion of theexcessive slack upper material thrown by the spring formation into thewaist of the last that it is removed and carried forward toward the toe,thus securing a better distribution of the material and a cleaner andbetter fit of the upper to the last. The oredrawing movements of thegrippers also stretch the upper longitudinally more or less. The tackingmechanisms at the opposite sides of the shoe secure the upper while itis in this stretched condition.

The sliding or guiding device may be so 7 fixed relatively to thegripper that only one range of movement lengthwise of the last isobtained for a given amount of updraw movement thereof or it may be inadjustable connection with the gripper by which means the extent ofmovement of the gripper lengthwise of the last in relation to the extentof the updraw may be varied as desired, or even reduced to zero in whichlatter instance the sliding or guiding device will be out of action orneutralized so as not'to produce any foredraw.

v Another convenient form of mechanism according to this invention foreffecting the foredraw movement of the side gripper for the purposehereinbefore described may consist of a frame or support reciprocatedupon bearings in the main frame of the machine and connected by a linkwith a side gripper. To operate the 'side gripper to effect the foredrawmovement this frame or support is reciprocated automatically or by hand,its link conveying the motion to the side gripper whereby the upper isgiven foredraw as before described. The gripper will be moved in the`direction of the length of the last by the reciprocation of the frameor support and it can be arranged to act ,either subsequent-ly to orsimultaneously with or prior to the updrawing according to the timing ofthe oscillations of the reciprocating frame relatively to the timing ofthe operations of the parts of the machine by which the updraw iseffected.

In a pulling-over machine in which as heretofore an adjusting mechanismis employed for adjusting the upper upon the last in or approximately inthe plane of the sole thereof which mechanism is usually termed the tipstraightening mechanism and whereby one of the side grippers can bemoved in one direction while the other side gripper is moved in theopposite direction a movement can be advantageously given to the supportcarrying the said mechanism, which movement will so operate the sidegrippers that they will be moved in a direction lengthwise of the lastto impart the foredraw to certain parts of the upper as hereinbeforedescribed, this foredraw device being arranged to act yieldingly when sodesired in order to avoid damage to the work being operated upon. Insuch a combined tip straightening and foredraw mechanism thereciprocating frame or support may for example carry a shaft or membercapable ofbeing partially rotated thereon by hand. The shaft or memberhas connected to it at opposite sides of its axis of rotation linksextending from and connected with the side grippers so that by rotatingthe shaft or member the side grippers will be moved in oppositedirections to effect the usual tipstraighteningadjustment of the upperupon the last. In such a tip-straightening and foredraw mechanism thatpart thereof by which the foredraw-is edected can be put into orout ofoperation and can also have the extent of its foredrawing movementvaried by a control device such for instance as is hereinafter describedwith reference to Figs. 8, 9 and 10.

That feature of my invention which includes effect-ing the foredrawmovement independently of the updraw movement is not herein specificallyclaimed as it forms the subject-matter of a divisional application,Serial No. 207,108, filed May 9, 1904.

In the accompanying drawings which illustrate examples of constructionsin which this invention is carried into practical effect:-Figure 1 is aside elevation of part of a pulling-over machine modified according tothe' present invention, being a portion of Fig. 3 of the drawings ofsaid Letters Patent N o. 663,777 altered to comprise one of thecombinations of devices according to the present invention. Fig. 2 is apart of Fig. 1 drawn to a larger scale and with a portion shown insection. Fig. 3 is a section on the line 3-3 of Fig. 1 drawn to a largerscale than that of Fig. 1 and indicating that the devices by whichengagement is obtained between the improved grlpper and the device overwhich it slides according to the present invention are the same as theparts that in the aforesaid prior Letters Patent are correspondinglynumbered; Fig. 4 is a side view, similar to Fig. 1 to illustrate amodified arrangement of the means whereby the foredraw motion isimparted to the gripper; Figs. 5 and 6 are views at right angles to oneanother of the lower part of a gripper similar to that shown in Fig. 1but with one element of the means by which the foredraw motion isimparted made so as to be adjustable to vary the extentof the foredrawmotion; Fig. 7 is an enlarged section of a part of Fig. 5. Figs. 8, 9and 10 are respectively a side view, a vertical section (on line 9-9 ofFig. 8) and a plan (on line 10-10 of Fig. 8) of part ofthe head of apulling-over machine to illustrate a further alternative arrangement inwhich the tip-straightening mechanism is movable bodily in order thatthe foredraw may be effected by that movement. Fig. 11 is a perspectiveof a detail of Figs. 8, 9 and 10 hereinafter specifically described.Fig. 12 is a vertical sectional view looking from the front of themachine, as from line 12 in Fig. l or Fig 8.

Like letters of reference indicate like parts in all the drawings, asdolike numerals.

Referring first to Figs. 1, 2 and 3 the framework B, (except that thoseportions of it which constitute guides for the gripper bar members 62have a little extra clearance in relation to the grippers in order toenable the gripper to move laterally far enough to give foredraw) thelever 154 pivoted on a pin 152 in that framework, the shaft D, the camX30 and the parts 134, 141, 143, 156, 68, 124, 62 together with thetacking mechanisms, including the arms 672 and tack blocks 600 locatedat each side of the machine for securing the upper in the position towhich it is pulled by the grippers are of the same construction as theparts correspondingly numbered in the specification of the aforesaidprior Letters Patent, as also are the parts 257, 256, 254, 252, and 244,the part 62 being acted upon as in the said Letters Patent by the lever154 so as to tend to move it in the direction of its own length; butaccording to the present invention there is a guide or groove 240X inthe gripper bar member 62 which unlike the groove 240 of the priorLetters Patent aforesaid is not parallel to the direction in which thegrippe-r would move to effect the updraw alone but is inclined thereto,that is to say in the present example it is at an angle to the axis ofthe gripper with its lower end farther from the gripper bar member thanthe upper end and is in or approximately in the plane in which thegripper is required to swing in effecting the foredraw. Consequently asthe member 62 is raised to cause the gripper to effect the updraw itwill be simultaneously caused by the interaction of the slide 244, whichfor the time being is intended to be kept stationary with regard to theframework B, with the inclined guide or groove 240X to have a componentof motion in the direction of the toe of the last L, that is, toward thetoe gripper to effect the foredraw, said last being held up by the handof the operator or by the action of the machin-e against lastsupportersor supported by a jack as may be desired. f foredraw is at any time notdesired the support 256 upon which the slide 244 is mounted may, insteadof being kept stationary be allowed to recede under the influence of thethust applied to it by the guide 240X during the updraw; the slide 244under suoli circumstances will no longer interact with the guide 240Xand thus goes out of action with respect to foredraw.

Although in the example illustrated in Figs. l, 2 and 8 the inclinedgroove is on the gripper and the device in relation to -which it hasmotion is virtually on the main framework of t-he machine, the converseof this arrangement might be adopted so that a gripper having aprojection stationary upon it engaged with an inclined groove on thestationary framework for the purpose of the obtainment of foredrawsimultaneously with updraw would be within the present invention.Various other mechanical arrangements may be devised within the scope ofthis invention for producing foredraw movement of the grippers eitherduring the relative movement of the last and grippers for pulling theupper about the last or prior to or subsequent to such pulling movement.

Although in the example above described the slide 244, being alreadypresent in a known type of machine can very conveniently be utilized tocoperate for the purposes of the present invention with the inclinedguide or groove upon the gripper bar member, any device which will causea gripper by reason of its updraw movement relatively to a stationaryframework such as B to receive simultaneously with such updraw aforedraw movement is within the present invention.

According to the modification illustrated in Fig. 4 of the drawings, thefo-redraw movement of the side gripper is obtained by a link econnecting the gripper bar member 62 with a point on the framework B ofthe machine, so placed that as the gripper is moved upward by the updrawmechanism the lower end of the link e connected with the gripper cannotdo otherwise than move in the direction of the arrow adjacent to itwhereby the gripper is constrained to move outward from the framework Btoward the toe of the last to eect the foredraw. The link c is connectedwith the framework B and gripper bar member 62 by ball and socket jointse', e2 respectively to permit angular movement of the link in relationto the gripper bar member 62 and the framework B not only in theforedraw and updraw but also in the usual overdraw movement. To renderthe gripper capable of yielding, the link e is made in two parts cx andex* telescopically arranged. The two parts are held in their extendedposition by a spring 7c which will yield when subjected to undue stress.

In the arrangement shown in Figs. l and 2 the amount of foredraw -givento the sidegripper depends on the degree of inclination of the guide orgroove 240X and the range of updraw movement of said side gripper. Inthe construction illustrated in Fig. 4 the amount o-f foredraw dependson the length of the link e and the angle it makes with the parts 62 andB when the gripper is at say, the lowest limit of its vertical travel,except as it may be modified by yielding of the spring X.

In the arrangement shown in Figs. 5, 6 and 7 a foredraw movement of theside gripper is obtained the extent of which can be varied relatively tothe updraw according to requirements. The guide 240X provided with theslot or groove 240XX instead of being rigidly secured to the gripper barmember 62 as described with reference to Fig. l, is in this case hingedto that member. A pivot pin f passes through an opening in the upperpart of the guide 240X and through other openings in lugs 62 projectingfro-1n the member 62. In the lower part of the guide 240X is a slot24()a in which an eccentric part g (see Fig. 7) of a control bolt g islocated, the bolt being centered in lugs 62a forming part of the gripperbar member 62. By turning the bolt g in the lug 62a the eecentricportion g engaging the slot 240a will cause the guide 240X to assume adesired angle so that the gripper will be moved a greater or a lesserdistance toward the toe vbearing Bo of the last upon its next upwardmovement. The part g of the control bolt g may if desired, be given adegree of eccentricity greater than that which it possesses in Fig. 7and sufficient to enable it to movethe guide S240X into parallelism withthe length of the gripper bar member 62. The control bolt g may thusserve to put into or out of action with respect to foredraw the portion240X of the mechanism which is adapted to give the foredraw motion tothe gripper, for when the guide 24e-0X is thereby put parallel with thelength of the gripper in which case it will be parallel with thedirection in which vupdraw occurs, the updraw will not bring aboutforedraw also. The head of the bolt g can be provided as shown with ascale g2 a corresponding' mark being arranged upon one o-f the lugs 62aso as to aiford an indicator for showing the amount of inclination towhich the guide 240X is adjusted, a fixing nut g3 being employed tosecure the bolt g when it has been rotated suiiiciently for the amountof foredraw required. Like degrees of foredraw movement or differentdegrees of foredraw movement may be imparted to different grippers wheretwo or more of them are employed according to this invention to effectforedraw. For instance, where two or more grippers are each providedwith the adjustable guide 24:0X of Figs. 5, 6 and 7 the guide-ways ifadjusted to different angles by their bolts g will receive differentamounts'of foredraw movement if each receives the same amount -of updrawmovement; by such devices the grippers receive different degrees offoredraw movement which are variable. Y

The alternativeV arrangement represented in Figs. 8, 9 and l0, shows atip-straightening mechanism which is arranged to eEect foredraw also,according to this invention. A frame or support 7b is secured to, andoscillates with. a shaft i turning in a in the framework B of themachine. An arm j loosely mounted upon the shaft i is provided at itsupper extremity with a bowl y" which engages in a camgroove of the cam Dkeyed on the main shaft D of the machine. A lug jz extending from thearm j carries a rod or spindle 7s which passes through a hole 71/ in aprojecting part 71.2 of the oscillating frame 7L; a spring 7c surroundsthe rod or spindle 7c and is held in compression between a handwheel 702screwed upon the threaded end of the rod or spindle 7c and theprojecting part 71,2. The projections jz and 71.2 are normally heldagainst one another by the spring 7c the degree of compression of whichcan be adjusted as desired by the wheel 7a2.' This spring connectionwill prevent undue stressing of the upper and allow the parts j2 and 7a2to separate before damage is done to the work being operated upon. Theoscillating frame or support 71. carries a shaft Z which is capable,(for a urpose hereinafter to be described), of in ependent partialrotary motion and the shaft has connected to it, by ball and socketjoints e', the ends of two links e, t-he links being connected to theshaft on opposite sides of its axial line, the other ends of the saidlinks e being connected b y other ball and socket joints e2 with theside gripper bar members 62. In order that the ends of the links e thatare in the ball and socket joints c may despite their connection withopposite sides of the shaft Z be equidistant from the axis of the shaftz' about which they are oscillated to impart the foredraw motion to thegrippers, the shaft Z is inclined in relation to the shaft z'. To'enablethe shaft Z to be partially rotated when desired an arm or lever m issecured upon one end of the said shaft and is connected by a link a withan arm 0 of another lever, centered upon the lframework B of themachine, the other extremity of the lever terminating in an operatinghandle 292.

In the operation of the machine constructed according to these Figs. 8,9 and 10, the arm j is oscillated by the cam D about the shaft i' asaforesaid. In its movement toward the left of an observer of Fig. 8there is applied a thrust by way of the projection j2, rod 7c, wheel 702and spring 7c to the projection 7b2 of the frame 7L, thereby moving thatframe in the direction of the right hand of an observer of that figureand by the links e moving each gripper bar member 62 in the samedirection to impart the foredraw, this motion being imparted through thespring 7c as described. The frame 7L, links c and gripper bar members 62can yield under control of the spring 7c should the resistance offeredby the work to the foredrawing operation exceed the force applied to itthrough the spring in the reverse direction. In the return movement ofthe arm y', that is to say movement toward the right of an observer ofFig. 8, projections jg and 7a2 come into contact with one another andthis insures the return of the gripper bar members 62 to their normalstarting position after each foredraw, which in this arrangement may beimparted either subsequently to or simultaneously with the updraw orprior to the updraw, this depending upon the setting of the cam D withrelation to the cam of the usual updraw mechanism also operated by theshaft D. The adjustment of the upper upon the last or tip-straighteningin this construction is effected by partially rotating the shaft Z aboutits own axis by means of the handle 292 so that one side gripper (by itslink e connecting it with one side of the shaft Z) is moved outwardly oraway from the frame, while simultaneously the other side gripper ismoved in the opposite direction or toward the frame by its own link econnected with the other side of the shaft Z; thus the two gripperscooperate to move the toe of the upper around the last. According to thedirection in which the handle 292 is operated the shaft Z will be turnedin one or the other direction this having the effect of causing thegrippers to straighten the toe toward one side of the last or the other.To vary the extent of the foredraw movement of the gripper bar member 62or to render that member entirely inoperative in respect to foredraw, ifso desired, a segment a; fixed on a shaft x can be provided, the shaftbeing supported in bearings in the main frame of the machine and beingadapted to be rotated either by a hand lever upon it or by connectionwith a pedal. The segment shown, with its shaft in Fig. ll separate fromthe machine has an inclined or wedgeshaped projection :r2 formed uponits face, so that by partially rotating the segment w some part of theincline will be brought into position to oppose the movement of theframe or support 7i, an adjustable bearingscrew h3 being screwed throughthe frame to afford a suitable bearing surface. Accoi-ding to the heightof the part of the incline rotated into posit-ion opposite the screw h3so will the movement of the frame or support be more or less restricted,the projection h2 on the frame h being thereby separated for acorresponding distance from the projection j2 on the lever j whichoperates it, the said projection 7'2 which has a constant range ofmovement being thus made operative upon the projection h2 throughvarying degrees of the range of the former. lVhen the highest part ofthe incline is brought opposite to the screw h3 any movement of theframe or support will be entirelyprevented.

It will of course be understood that this invention is not limited tothe embodiments thereof herein described and shown but that theinvention may be embodied in other constructions and is broad enought tocover any means by which the grippers can be actuated to impart to theupper a foredraw movement. Mechanism for moving the grippers forwardlyto impart foredraw independently of the updraw, an example of which isshown in Figs. 8 to 11, is not herein claimed but is claimed in thedivisional applicaton before mentioned.
